TYIErWRITING MAGHINE. p X

. Specified To all whom it mm} m: Q

Be it known the IARLES S. LABOFISH, citizen of the Uniter States, and resident of District-of Columbia, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a s ecification. My invention relates to ribbon mehanism for typewriting machines and one of the ob-' .jects of said invention is to provide a'simple, cheap, and efficient poly chrome ribbon mechanism of mechanism for writing with inks having different characteristics.

A further object of my inventionis, to provide a simple; cheap and efficient device which is in the nature of-an attachment that plied to existing forms of mes without changing tlhe structural atures of such machines and I means owhichdifiirent colors or different characters 1 co ymg. or

of inks or inking surfaces, such as record ribbons or mkm surf cemcan-be' employed and any one o which may be readilybrought into operation the features 0 no.0. thine, though it i may beapplied to.

without loss of another.

To the above and other ends which'will hereinafter ap ear, my invention consists in construction arrangement of arts and combinations devices to t be" ereinafter describ d and particularly pointed out in the appended claims: In the drawings, Figure 1 is a diagram: matic vertical front to rear sectional view of sufficient number of partsof a typewriting machine-to illustrate the features of my in-- vention and their ap lication thereto. Fig. 2 is a fragmentary etailtop plan view of certain i; the parts of the machine, showing the feat'uresof my invention applied thereto. Fig. 3is an enlarged detail transverse sectional view. taken on the line x-m of Fig. 2.- Fig. 4 is a detail front elevation of the parts shown in Fig. 2. Fig.- 5 is a fragmentary plan view showing parts of 9. No.6 Remington machine with the devices of my invention applied thereto. ;I have shown y invention applied in the present instance to a No. 6 Remington mais obvious that the invention other forms of type-writtime in changing from one to mg machines.

The laten 1 isdiagramiriatically illustrated m-Fig. 1; the type bars or printing instrumentalities 2 being actuated and co or Letters Patent.

manner ployed in the No. 6.;R-cmihgton machine 00- opprates in. the usual manner with the r1 bon 4 to guide it in its longitudinal fee movement from one spool ribbon passing across an 0 ribbon guide, through against the platen or the n In the longitudinal feed of the ribbon it is aided by fingers-3 each supported at its orward. end on the guide plate and o ening at the rear to receive the ribbon as s own in Fi ening 5 in the Pivoted at a 1 suitable point, preferabdy upon .theribben" guide 3, is a carrier 6 which spreferably-in 'theinature of a lever. pivoted'at 7 to the uide and providedwith a finger piece or audio 8 which extends from the under side of the 'id'e plate where the lever is situated throug a segmental slot 9 in the ribbbn guide sidethereof, as indicated m Fi s. 2 and 4. The inner end'of the lever is bi cated at 10 for cooperation with a circumferential groove 11 in a pivot stud 12. The grooved portion/l1 of the stud has two oppositely disposed flattened w ich the for I lever is adaptedto' cooperate in order to constudto the lever and to prevent the stud Thereis sufiicient frictional contact between the stud and the seat in the lever to hold the stud inv place against accidental displacement from the lever, but the stud me. be withdrawn from the forked end of the ever when desired.

The pivot stud has a portion 14 with a head 15 at the lower e thereof. The bearing portion of the stud is .adapted to be projected through a central bearing 0 eniug. in an Jnkmg disk 16 that is reinforce bya thereto and is the stud and is adapted to be seated-with the stud so as to 've a ter rigidity to t e disk and to a 0rd 8. etter bearing therefor on the stud. When the stud is seated in the forked end of the lever the disk is locked on the stud and cannot be removed except by removing the ,stud from its seat in the lever. From an examination of Fi 4 it will be seen that the bifurcated end 0 the lever 6 is thinner, as shown at 18', than the body porwalls 13 with' ed or bifurcated endofthc from turning on the lever.'

to another,. the

who the types are cylindrical bearifig inking ribbon, thereby utilizing .tudinal feed of the tion of the lever, in order that the head 19 of the pivot stud, when seated in the bifurcated portion of the lever, will not interfere with the movement of the lever on-its pivot 7 and 80 that the inking disk 16 may be maintained close to the ribbon guide plate 3. It will be observed that the inking disk 16 is located above the ribbon or main inking device 4 and is adapted to be interposed between the ribbon 4 and the platen andin the path of the printing instrumentalities. It will also be seen that when the inking disk is in the 0 erative osition illustrated in full lines in Fig.- 2-{an in Fig. 5, one side of the disk is maintained in contactwith the inkin ribbon 4 (seeFig. 4) and that the automatic longiribbon effected in the usual manner from the spring drum 20 through the parts 21, 22, 23, 24, 25 and 26 will rotate the disk on its pivot. --The ribbon uides 3 assist in maintaining this contact etween the ribbon and inking disk to insure a rotary movement being transmitted to the disk from the linking ribbon. ribbonguide 3 is automatically moved back and forth in a transverse direction during the longitudinal feed of the ribbon, as in the N o. 6 Remington machine by the parts 27 to 33 inclusive, the disk willreceive an automatic feed radially of its pivot as well as a rotary feed effected by reason of its contact with the ractically the entire lnking surface on the dislk.

Then the disk is moved by its lever 6 to the dotted line position in Fig. 2 it is carried out of contact with the'ribbon 4 and is maintained in osition-where it will not be interposed in t e path of the printing instrumentalities. The auxiliary inking device or disk 16 may be red, or of a distinctive color or characteristic from the main inking device or ribbon 4. Thus, the ribbon 4 may be record ribbon and the inking disk may be copying'- ribbon or an inking surface carryin copying ink.

hen itis desired to change the color or characteristic of the imprint from that produced by the cooperation of the printing instrumen'talities with the ribbon 4 1t is merely necessary to shift the lever 6 from the dotted line position to that indicated bypthe full lines in Fig. 2. When the inking disk 16 is interposed in the path of the printing instrumentalities, the types will impact in the first instance on the ribbon 4 and the impression will be made through the disk 16 which, being next to the paper, will produce the writingv in accordance with the characteristic ofthe ink on the disk 16. When a, fixed ribbon diiterent radial portions of the disk may be used by moving the handle or finger piece 8 by hand so as to bring the points of impact of the types at different distances from the pivotal center of the disk, so that the imguide is employed circles as the disk is the No. i 6 Remington, without When the pacts may take place in different concentric automatically rotated around its pivotal stud 12. It will be understood that there'is sufficient frictional contact between the lever and the ribbon guide plate 3 to maintain the lever in any position to which it is moved,so that the adjustmentof the disk to different radial ositions by means of the lever 6 can be rea ily effected.

From the foregoing description it will be seen that I am enabled to provide a simple, inexpensive and efiicient auxiliary inking device that may be readily applied to existingforms of typewriting machines, such as changing the structural features of such machine, and that the ordinary feed mechanisms employed in such machines for feeding the ribbon may be a a radial feed of the auxiliary inking disk of my invention.

Various changes in the details of construction may be made without departing from the s irit of the invention.
